[0028] To make the objectives, technical solutions, and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Examples of embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] This utility model discloses a rotary gripping pliers, please refer to Figure 1 The operating part 10, the connecting part 20 and the gripping part 40 are connected in sequence along the arrangement direction, including a rotating part 30 rotatably connected to the connecting part 20, the rotation axis of the rotating part 30 is perpendicular to the arrangement direction, the gripping part 40 and the rotating part 30 are fixedly connected, the operating part 10 is connected to the controller 11, the rotating part 30 has a first angular position and a second angular position, when the controller 11 sends a control signal, the rotating part 30 rotates between the first angular position and the second angular position.

[0030] The control part 10, the connecting part 20, the rotating part 30 and the gripping part 40 are connected in sequence along the arrangement direction. The rotation axis of the rotating part 30 is perpendicular to the arrangement direction, so that the gripping part 40 can rotate relative to the connecting part 20 through the rotating part 30. The control part 10 is connected to the controller 11, and the control signal sent by the controller 11 can control the rotating part 30 to rotate at a first angle position and a second angle position. In different operation links, the posture of the gripping part 40 can be changed by controlling the control part 10. When the postures of the control part 10 and the connecting part 20 do not change, the angle and posture of the gripping part 40 are changed, so that the blood vessels or other tissues can be better clamped. Compared with the prior art, the rotary gripping forceps disclosed in the present application can meet the diverse needs of operations during surgery.

[0031] Specifically, the control portion 10 is typically held by the operator and used to control the movement of the entire rotating gripping forceps. The connecting portion 20 is positioned at a certain distance. The longer connecting portion 20 allows the rotating gripping forceps to be easily inserted into the human body. The connecting portion 20 connects the control portion 10 to the gripping portion 40, which performs the clamping function. The gripping portion 40 can be detachably connected to the rotating portion 30 or directly fixedly connected to the rotating portion 30. This detachable connection allows the operator to easily select the appropriate gripping portion 40.

[0032] Among them, the controller 11 and the rotating part 30 can be connected in a mechanically controlled manner, so that the rotating part 30 can rotate between the first angle position and the second angle position; the controller 11 and the rotating part 30 can also be connected in an electrically controlled manner, so that the rotating part 30 can rotate between the first angle and the second angle position.

[0033] In some embodiments, please refer to Figure 1 The gripping portion 40 has a clamping plane, and when the rotating portion 30 is not rotating, a plane formed by the arrangement direction and the rotation axis of the rotating portion 30 is parallel to the clamping plane.

[0034] The clamping plane refers to the plane formed by the clamping claws of the gripping portion 40 when clamping. In this embodiment, the description is based on the state when the rotating portion 30 is not rotating. At this time, the default arrangement direction is parallel to the clamping plane or located within the clamping plane. At this time, the plane formed by the arrangement direction and the rotation axis of the rotating portion 30 is also parallel to the clamping plane. It should be noted that when the formed plane and the clamping plane when the rotating portion 30 is not rotating are the same plane, it still falls within the scope of protection of this embodiment. By rotating the rotating portion 30 in this rotation direction, the clamping plane can be rotated around the rotation axis to meet more needs during the operation.

[0035] In other embodiments, the rotation axis of the rotating portion 30 may also be perpendicular to or intersect with the clamping plane, so as to adapt to the use of the rotary grasping forceps in different scenarios and achieve a better clamping effect during the surgical process.

[0036] In other embodiments, the rotating grasping forceps is further provided with a rotating shaft portion, and the rotating portion 30 is connected to the connecting portion 20 via the rotating shaft portion. The rotating axis of the rotating shaft portion is the arrangement direction, thereby realizing the grasping of the rotating grasping forceps at more angles. The rotating shaft portion can be manually screwed, and a control switch can also be provided for control, and the control switch can be provided on the control portion 10.

[0037] In some embodiments, please refer to Figures 1 to 4The controller 11 includes a transmission part 12 and a control button 13 , and the control button 13 is connected to the rotating part 30 through the transmission part 12 .

[0038] Specifically, the controller 11 includes a transmission unit 12 and a control button 13. An operator operates the control button 13 to move the transmission unit 12, which in turn drives the rotating unit 30 to rotate. It should be noted that mechanical control offers greater stability and less maintenance than electrical control. Mechanical control also avoids the generation of electrical current that could interfere with medical devices installed in the human body, potentially impacting their proper use, and offers improved safety.

[0039] In some specific embodiments, please refer to Figures 1 to 4 The transmission part 12 is a rack, the rotating part 30 is a gear, the rack and the gear are meshed with each other, the control button 13 is connected to the rack, the gear and the gripping part 40 are fixedly connected, and the control button 13 pushes the rack to move along the arrangement direction.

[0040] Specifically, the rack and the gear are meshed with each other. When the operator operates the control button 13, the rack will move along the arrangement direction, causing the gear to rotate, and then drive the gripping part 40 fixedly connected to the gear to rotate, thereby achieving the purpose of changing the angle and realizing the diversified needs of the surgical process.

[0041] For more specific examples, please refer to Figures 1 to 4 The rack is connected to the gear through the intermediate wheel 14, so that the transmission ratio is more flexible and the arrangement between the rack and the gear is more flexible, thereby better meeting diversified needs. Among them, the intermediate wheel 14 can be a planetary wheel or a coaxial wheel.

[0042] In some more specific embodiments, the rotating portion 30 further includes a groove-shaped limiting structure 31 , and the gear is provided with a protruding structure 32 , which is located inside the limiting structure 31 .

[0043] In order to facilitate the control of the rotation angle of the rotating part 30 and prevent it from rotating beyond a certain limit and causing harm to the human body, a limiting structure 31 is provided on the rotating part 30, and a protruding structure 32 is provided on the gear. The protruding structure 32 can move in the groove-shaped limiting structure 31. When the protruding structure 32 abuts against the edge of the groove, the rotating part 30 cannot rotate further, thereby achieving the purpose of limiting.

[0044] For some particularly specific embodiments, please refer to Figures 1 to 4The rotating part 30 is located in the hollow cylinder 33, and a groove-shaped limiting structure 31 is opened in the circumference of the hollow cylinder 33. The rotating part 30 can rotate in the hollow cylinder 33. The setting of the hollow cylinder 33 can protect the rotating part 30 on the one hand, and on the other hand, the arrangement of the limiting structure 31 is reasonable and will not take up more space.

[0045] In some particularly specific embodiments, the gear is fixedly connected to the gripping portion 40 via the protruding structure 32. This allows the protruding structure 32 to have both the limiting and connection functions, further optimizing the overall layout of the rotary gripping forceps, making the overall size smaller and the structure more compact.

[0046] For more specific examples, please refer to Figures 1 to 4 The connecting portion 20 has a connecting rod 21 for controlling the clamping, and the rack is arranged on the connecting rod 21.

[0047] Specifically, the gripping portion 40 can be controlled to achieve the clamping operation by controlling the connecting rod 21. In order to reduce the size of the rotary gripping forceps so that it can be used in a smaller space, the rack is provided on the connecting rod 21 to make the overall structure more compact.

[0048] In some more specific embodiments, the control button 13 is a grip wrench. When two ends of the grip wrench move closer to or farther from each other, the rotating portion 30 rotates between a first angular position and a second angular position.

[0049] It should be noted that the use of the gripping wrench can improve the convenience of the operator in operating the rotary gripping pliers. On the one hand, the operator can control the movement of the entire rotary gripping pliers by gripping the wrench, and on the other hand, the operator can grip the wrench to control the rotation of the rotating part 30.

[0050] In some more specific embodiments, an elastic rod 15 is provided between the two ends of the gripping wrench to restore the gripping wrench to its initial state, making it easier to operate.

[0051] In some embodiments, the rotation angle can be 0° to 180°, so as to adapt to more application scenarios and obtain a better clamping posture.

[0052] In some specific embodiments, the transmission part 12 is a reset pull rope box, which includes a box body, an elastic reset part and a pull rope. The pull rope is wound on the box body, and the box body and the rotating part 30 are fixedly connected. One end of the pull rope is connected to the elastic reset part for resetting, and the other end is connected to the control button 13. The control button 13 pulls the pull rope to move along the arrangement direction.

[0053] Specifically, the transmission portion 12 is a pull-cord box. The operator can pull the pull cord by controlling the control button 13. One end of the pull cord is connected to an elastic reset member to maintain it in its initial position, and the other end is connected to the elastic reset member. When the pull cord is pulled, the box body rotates, thereby causing the rotating portion 30 to rotate simultaneously. When the pull cord is released, the reset elastic member can reset the pull cord from its original position after being pulled to its initial position. In some embodiments, the rotating portion 30 is a box body. The elastic reset member can be a torque spring, and the control button 13 can be a knob.

[0054] In some embodiments, the rotating part 30 is a servo motor, and the servo motor is connected to the controller 11 by signal.

[0055] It should be noted that the rotating portion 30 is servo-electric, and the servo motor can be connected to the controller 11 by signal, and the signal connection method can be wireless or wired. This avoids the need for additional transmission structures, making the rotary gripping forceps lighter and reducing the burden on the operator's wrist when using the rotary gripping forceps.

[0056] In some specific embodiments, the controller 11 is a stepless controller 11 having a first gear and a second gear. When the stepless controller 11 moves between the first gear and the second gear, the rotating part 30 rotates between the first angular position and the second angular position.

[0057] Specifically, the controller 11 is a stepless controller 11. When moving between the first gear and the second gear, each position of the stepless controller 11 corresponds to a rotation angle of the rotating part 30, so that the operator can make fine adjustments according to the specific usage scenario.

[0058] In other embodiments, the controller 11 has multiple gears. By adjusting different gears, the rotating part 30 is at a specific angle. In this way, the rotating part 30 can only be adjusted to a specific angle. The number of adjustable angles is determined according to the number of gears of the controller 11. The angle of the rotating part 30 can only be roughly adjusted, but its cost is relatively low.
